Iranian President Mahmoud Ahmadinejad says the UN headquarters should be moved to a free land where its operations and decisions will not be undermined.
"The UN should be in a free place, away from US domination," Ahmadinejad, who was speaking at the end of the Group of Eight Developing Countries (D8) in the Nigerian capital Abuja, said on Thursday, Press TV reported.
He added that the US imposes itself on international organizations like the United Nations and undercuts their efforts, IRNA reported on Friday.
The Iranian chief executive further added that the US has appropriated the power to grant visas for UN members to participate in its sessions, while the authority should lie with the UN.
He also criticized nuclear-armed states that have the veto power in the UN Security Council and "dominate" it.
Ahmadinejad noted that the US exploits other countries with "fiat dollars" and uses the currency as leverage in its global transactions.
He further noted that the new UN sanctions against the Islamic Republic will have no effect on its nuclear energy program.
The US and its Western allies accuse Iran of seeking to build atomic weapons, a charge that Tehran rejects, describing its nuclear activities as purely civilian.
On Friday, Ahmadinejad returned home after his African tour. He described his tour of Africa, which included visits to Mali and Nigeria, as positive.
